Subject: Turning the __w64 attribute into an ignored attribute to match other Microsoft extens... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=328b3ffb155c94e8ab54b0f282d8db6a1f839deb;p=clang

Turning the __w64 attribute into an ignored attribute to match other Microsoft extensions we do not currently support. Note that __w64 has been deprecated in MSVC since 2008.
